Answer:

Step-by-step explanation:

Example:

You have no money, you decide to swipe your credit card to purchase something for $17. Again, you did so for another item paying $24. You are now $41 in debt. Your mom decides to pay for your debt which is $41. You decide to actually go to your part-time job and earn $23. When was the time you had the most money in this example? When you earned the $23 becuase you started with none.

Answer:

Step-by-step explanation:

Out of the numbers given:

All positive numbers are greater than negative numbers.

This eliminates -17 and -24.

Comparing 0 to 23:

23 has more value than 0.

0 < 23

This means out of the numbers given, 23 has the greatest value.

Hope this helps.

What is the domain and range of quadratic function with vertex.

Alexus [3.1K]

Answer:

As with any function, the domain of a quadratic function f(x) is the set of x -values for which the function is defined, and the range is the set of all the output values (values of f ). Quadratic functions generally have the whole real line as their domain: any x is a legitimate input. The vertex will be the minimum (lowest point) of the graph if and the maximum (highest point) of the graph if

Consider the equations 4(x-3)=16 and 4x-3=16 do they have the same solution? Why or why not ?

Sladkaya [172]

Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation

Solution:

4 (x-3)=16

4x - 12 = 16

4x = 16 + 12

4x = 28

x = 7

4x - 3 = 16

4x = 16 + 3

4x = 19

x = 19/4

x = 4.75

Please help !!!! urgent

Finger [1]

Answer:

$P(x) = 16x - 100 - 0.1x^2$

Step-by-step explanation:

Given

$R(x) = 46x$

$C(x) = 100 +30x +0.1x^2$

Required

Determine the profit function

This is calculated as follows:

$P(x) = R(x)- C(x)$

Substitute values for R(x) and C(x)

$P(x) = 46x - (100 + 30x + 0.1x^2)$

Open bracket

$P(x) = 46x - 100 - 30x - 0.1x^2$

Collect like terms

$P(x) = 46x - 30x - 100 - 0.1x^2$

$P(x) = 16x - 100 - 0.1x^2$

For 7 and 8, find the maximum or minimum point of the parabola

Leni [432]

Answer: 7) Max: y = 52

8) Min: y = -51

<u>Step-by-step explanation:</u>

The Max/Min is the y-value of the intercept.

Max is when the a-value is negative.
Min is when the a-value is positive.

First, find the x-value of the vertex using the Axis of Symmetry formula:

x = -b/2a. Then plug the x-value into the equation to find the y-value.

7) y = -2x² - 16x + 20

↓ ↓ ↓

a= -2 b= -16 c=20

$\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(-16)}{2(-2)}\quad =\dfrac{16}{-4}\quad =-4$

Max: y = -2(-4)² - 16(-4) + 20

= -2(16) + 64 + 20

= -32 + 84

= 52

*********************************************************************************************

7) y = x² + 12x - 15

↓ ↓ ↓

a= 1 b= 12 c= -15

$\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(12)}{2(1)}\quad =\dfrac{-12}{2}\quad =-6$

Max: y = (-6)² + 12(-6) - 15

= 36 - 72 - 15

= 36 - 87

= -51
